An attorney for a man on Missouri’s death row says her client is on “an emotional roller coaster” amid efforts to spare his life with just a day to go before his scheduled execution. Michael Tisius is set to die by injection Tuesday evening for killing two jailers in 2000 in an ill-fated effort to free a man from a county jail. A clemency request before Republican Gov. Mike Parsons focus on several issues. Tisius was just 19 at the time of the killings; he was neglected as a child; and a juror at his 2010 resentencing may have been illiterate. The U.S. Supreme Court on Monday declined to halt the execution based on Tisius’ age when the crime occurred.
